BOTTLE.

SPECIFICATION forming part of Letters Patent No. 603,108, dated April26, 1898. Application filed April 20, 1897. Renewed March 24, 1898.Serial No. 675,042. Clio model.)

To all whom it may concern:

Be it known that I, PHILIP LINDEMEYR, a resident of Baltimore, in theState of Maryland, have invented certain new and useful Improvements inBottles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

The invention relates to bottles, and has for its object toprovidebottles with improved caps easily formed and securely fastened andsealed upon said bottles; and the invention consists in the constructionhereinafter described and pointed out.

In the accompanying drawings, Figure l is a side elevation of a bottle.Fig. 2 is an enlarged top plan of the same. Fig. 3 is a bottom plan of abot-tle-cap. Fig. 4 is a blank for forming the cap. Fig. 5 is a verticalsection of bottle top and cap. Fig. 5 is a similar view of amodification. Fig. 6 is a top plan of cap. Fig. 7 is an enlarged sectionof cap. Fig. 8 is a central section of a modified bottle neck and cap.Fig. 9 is a partial similar view of the same on an enlarged scale. Fig.10 is a similar view, the cap-holding finger being broken away. Fig. 11is a side elevation of a bottle -neck having its mouth closed by a cap.Fig. 12 is a plan of a cap. Fig. 13 is a similar view of thebottle-mouth. Fig. 1a is a section on line 14: 14 of Fig. 9. Fig. 15 isa section of a modified detail.

The main part of the bottle and bottle-top may have any desired form andsize, but will preferably have a top of frusto-conical form, as shown inFig. 1, and will have overhanging parts at diametric point-s forengaging fingers on the bottle-cap.

Numeral 1 denotes transverse grooves or depressions formed in and onopposite sides and on the outside of the neck to form said overhangingparts. Each groove 1 is connected withasimilar depression or groove 6,extended to the bottle-mouth.

3 denotes a cap, which may be stamped or formed in any usual way out ofsheet metal and formed by one or more operations, as found convenient.

In Fig. 4 the numeral 2 denotes a plain blank suitable for forming thecap with locking-fingers i and depressed center 5, the outline of thecap-top being indicated by the dot ted circle, and the line for bendingthe fingers being also indicated by short dotted lines.

The cap is of frusto-conical form and fits the bottle-top. In applyingit to the top it is pushed down thereon, each finger 4 being in thevertical groove 6, until the cap can be slightly turned to engage thefingers under the inclined upper walls of the transverse depressions orgrooves 1.

Grooves substantially such as shown are preferable to projecting ribs,for the reason that the latter require longer engaging fingers, which inuse are more exposed or outwardly projecting than such short ones as maybe used with grooves, and the preferred construction also presents abetter appearance.

-Between the depressed portion 5 and the approximately vertical wall ofthe cap is an annular groove 7, situated directly over the wall of thebottle-mouth.

8 is a disk of plastic material, which may be compounded, having thegeneral characteristics of shoemakers wax, and 9 denotes a cover, ofprepared or parchment paper or fabric, situated on the lower side of thedisk and of a character to resist weak acids.

In the preferred form shown in Figs. 1 to 5 the relative situation andfit of the bottletop in the cap with respect to groove 7 is such thatthe composition and paper disks it hardpressed are pushed into theannular seat 7, there being no room for outward pushing of the materialsexcept in the small depressions between the corrugations 10. Saidcorrugations are in the drawings eitaggerated in respect to their lengthand depth for the sake of clearness. They provide the equivalent of amilled periphery and in addition provide interior receptacles for theplastic material, portions of which being crowded therein act .by theirincrease of friction and adhesion as anchors to hold in place the mainparts of said packing, the corrugations thereby performing two usefuloffices.

It will be understood that the corrugations can be formed within avertical line passing through their foot, as indicated by dotted line inFig. 7, to provide for withdrawal of die.

The groove 7 is practically filled by the composition whenever the capis applied to the bottle, and no space for the outward expansion of thematerial under pressure exists except the small spaces between thecorrugations, as already stated. It is therefore difficult under anyconditions to cut the packing in applying the cap to the bottle. Thesmall portions of material crowded between the corrugations act byadhesion to hold the packing in when the cap is removed from the bottle.

On Sheet 2 the overhanging parts are shown as ribs 1, projectingoutward, the lower sides thereof being inclined and having one or morenotches 2 to engage the cap-holding fingers. These projections arepreferably molded on the bottle.

3 indicates a cap, which may be made of block-tin or other metal. It isprovided with depending fingers or hooks 4:,termiuating in inturnedextremities 5, adapted when the cap is suitably placed on the bottle toengage under the inclined ribs and enter one of the notches 2.

6 indicates beads, corrugations, or fiexures formed in the dependinghooks or fingers at to impart to them some degree of elasticity. Theseare not essential in all cases and, if used, need not be of theparticular form, number, or extent indicated. It is, however, desirablethat these hooks or fingers be sufficiently elastic to be sprung intoand out of notches 2 when the cap is screwed on or off the bottle-neckby rotating it to move said fingers along under the inclined ribs. Thenotches serve to prevent accidental removal or looseningof the cap; butthe construction is such that it can be removed and reapplied atpleasure.

7 denotes an annular groove formed in the cap, milled or corrugated, asindicated at 10', a little more at one side than shown in Figs. 5 and 7,to receive the edge of a plastic packing-disk 8. The extension of theedge of this disk into the groove insures that the joint between thecontiguous vertical walls of the cap and bottle-neck shall be covered orpacked. It is further provided that the disk 8 shall be securelyretained in the cap when removed. The plasticity of the disk insuresthatits edge can be crowded into the groove and remain therein.

A wax such as before named is used for the disk because it is notaffected by many weak acids, has no ofiensive odor, and retains theshape imparted to it. Being properly placed within the cap and thelatter being screwed over the bottle-mouth, the joint between the capand bottle is thoroughly packed. The paper cover for the disk,consisting of one or two circles, is by many weak acids not injuriouslyaffected. It improves the appearance of the disk besides protecting itagainst the bottle-mouth.

The above-described cap-stoppers are capable of general use, though theyare particularly applicable to bottles containing medicinal orproprietary remedies or other liquids intended to be kept in the bottleand used therefrom a portion at ,a time.

Having described my invention, what I claim is- 1. The combination ofthe frusto-conical cap with a bottle having a similarly-shaped top, saidcap having a groove 7 in its vertex, and contiguous corrugations l0surrounding its top below said groove, the exterior of said corrugationsbeing situated within the greatest circumference of the cap to permitwithdrawal of a die and providing receptacles for packing and anexterior holdingsurface for the fingers in rotating the cap,substantially as described.

2. The combination of the frusto-conical cap with a bottle having asimilarly-shaped top, said cap having a groove 7 in its vertex, andcontiguous corrugations 10 surrounding its top below said groove, theexterior of said corrugations being situated within the greatestcircumference of the cap to permit withdrawal of a die and providingreceptacles for packing and an exterior holding-surface for the fingersin rotating the cap, a plastic packing, a paper cover for the same, saidgroove and corrugations affording communicating receptacles for theplastic packing, substantially as described.

3. The combination of the frusto-conical cap having verticalcorrugations l0 and a horizontal communicating groove 7 situateddirectly over the bottle-lip and integral fingers 4, with the bottlehaving a frusto -conical top and grooves 6 terminating in transversegrooves 1, a packing situated in said groove and corrugations, andparchment or the like situated between the bottle-lip and the packing,substantially as described.

4. In a bottle the combination of a cap with a packing of plastic waxand a cover of parchment, prepared paper or the like, to prevent thecutting of said wax, the parchment being interposed between the wax andthe bottlelip, substantially as described.

5. The combination of a bottle provided with inclined shoulders thereon,a cap provided with a circumferential groove and with pendentspring-fingers adapted to engage under the shoulder, a packing ofplastic wax, and a paper cover for the bottom of the packing and betweenit and the wax to obviate the cutting of the same, the cap being adaptedin cooperation with the bottle-mouth to press the plastic material intothe groove, said material remaining fixed in the groove, substantiallyas described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
